This book is devoted to shells, a natural or human construction, whose modelling as a structure was particularly developed during the 20th century, leading to current numerical models. Many objects, in industry or civil engineering, come under shell mechanics, so a good knowledge of their behaviour and modelling is essential to master their design. The book highlights the very strong link between the deformation of geometric surfaces and the mechanics of shells. The theory is approached in a general formulation that can apply to any surface, and the applications bring the concepts and the methods of resolution to practical situations. It aims to understand the behaviour of shells and to identify the most important parameters, thus allowing a good interpretation of the numerical results. The reader will be able, with finite element software, to reproduce the proposed solutions. The book is based on the knowledge acquired by the reader in structural mechanics and provides essential information on the geometry of surfaces. It is ideal for students in the fields of engineering using mechanics, as well as professionals wishing to deepen their knowledge of shells.

This book presents new guidelines for the control of cracking in massive reinforced and prestressed concrete structures. Understanding this behavior during construction allows engineers to ensure properties such as durability, reliability, and water- and air-tightness throughout a structure’s lifetime. Based on the findings of the French national CEOS.fr project, the authors extend existing engineering standards and codes to advance the measurement and prediction of cracking patterns. Various behaviors of concrete under load are explored within the chapters of the book. These include cracking of ties, beams and in walls, and the simulation and evaluation of cracking, shrinkage and creep. The authors propose new engineering rules for crack width and space assessment of cracking patterns, and provide recommendations for measurement devices and protocols. Intended as a reference for design and civil engineers working on construction projects, as well as to aid further work in the research community, applied examples are provided at the end of each chapter in the form of expanded measurement methods, calculations and commentary on models.
